CVE-2024-41969
Missing Authentication for Critical Function (CWE-306)
Summary
A low privileged remote attacker may modify the configuration of the CODESYS V3 service through a missing authentication vulnerability which could lead to full system access and/or DoS.
Impact
This vulnerability allows a low-privileged remote attacker to modify the configuration of the CODESYS V3 service. The potential impacts are severe, including: 1. Full system access: The attacker could gain complete control over the affected system. 2. Denial of Service (DoS): The attacker could disrupt the normal functioning of the system, making it unavailable to legitimate users. The CVSS v3.1 base score is 8.8 (High severity), with the following metrics: - Attack Vector: Network - Attack Complexity: Low - Privileges Required: Low - User Interaction: None - Scope: Unchanged - Confidentiality Impact: High - Integrity Impact: High - Availability Impact: High This indicates that the vulnerability is relatively easy to exploit remotely and can have significant impacts on the confidentiality, integrity, and availability of the affected system.
Exploitation
There is no evidence that a public proof-of-concept exists. There is no evidence of proof of exploitation at the moment.
Patch
The vulnerability data provided does not mention any specific patch information. The security team should check with CODESYS for the latest security updates or patches addressing this vulnerability.
Mitigation
While no specific mitigation steps are provided in the vulnerability data, based on the nature of the vulnerability (missing authentication for critical function), the following general recommendations can be made: 1. Implement strong authentication mechanisms for all critical functions, especially those related to configuration changes in the CODESYS V3 service. 2. Limit network access to the CODESYS V3 service, allowing only trusted IP addresses or networks. 3. Monitor and log all access attempts and configuration changes to the CODESYS V3 service. 4. Implement network segmentation to isolate systems running CODESYS V3 from other parts of the network. 5. Apply the principle of least privilege, ensuring that users and processes have only the minimum necessary permissions. It's crucial to consult with CODESYS for specific mitigation strategies and to check for any available security updates or patches.
